CARL LEE ROSS, OF WILSON, NORTH CAROLINA.

TAPE-DISPENSING MACHINE.

Application filed. August 13, 1924. Serial No. 731,812.

To all whom it may concern:

Be it known that I, CARL LEE Ross, a citizen of the United States, residing at l/Vilson, in the county of Wilson and State of North Carolina, have invented new and useful Improvements in Tape-Dispensing Machines, of which the following is a specification.

This invention relates to improvements in machines for dispensing paper adhesive tape, such as is commonly used in substitution for wrapping cord;

An object of the present invention is to provide a machine from which paper adhesive tape may be fed andapplied to a bundle or other object with a single operation.

Another object of the invention is the provision of a machine of this character whereby pressure of the bundle or object thereon will both out and apply the tape and thus render it unnecessary forthe operator to handle the tape, which handling frequently renders the hands or fingers of the operator sticky.

Another object of the invention is the provision of a tape dispensing machine which may be adjusted so as to deliver strips of tape of the same length, or from which a strip of tape of any desired length may be removed.

WVith the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is an elevation of a machine constructed in accordance with the invention.

Figure 2 is a longitudinal sectional view of the same.

Figure 3 is a transverse section taken substantially on the line 3-3 of Figure 2.

Figure 4 is a top plan view of the machine.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the machine in the form disclosed comprises a base 10 and a top or plate 11, the latter being connected to and yieldably supported by the base upon springs 12, whereby the top 11 may be moved with respect to the base. Various means may be provided for guiding the top in its movement, one ofwhich consists of a vertically disposed post or standard 13 over which operates a sleeve 14 which extends downwardly from the top 11 and which has a sliding fit upon the post or standard 13.

Rotatably mounted in suitable brackets carried by the top plate 11, as indicated at 15 is a tape roll 16, one end of the tape extended through an opening 17 provided in the sleeve 14: so as to be positioned within this sleeve beneath the upper edge of the latter the sleeve being open at the top so as to provide an opening 18 in the cover plate 11.

Rotatably mounted between-the roll 16 and the sleeve 14 and carried by the cover plate 11 is a pair of rollers 19 and 20, while spaced from these rollers and also carried by the cover plate 11 is a roller 21. R0- tatably mounted beneath this last mentioned roller and cooperating therewith are spaced disks 22, the rollers 19, 20 and 21 and the disks 22 serving as a guide for the strip S of the tape and for feeding the tape into the sleeve, as will be hereinafter apparent. The rollersare corrugated to facilitate the feeding operation.

The tape has applied to one side a suitable adhesive which when moistened will cause the tape to adhere to an object and in order to moisten this side of the tape there is provided a moistening device in the form of an atomizer 23, the tube 2 1 of which is flexible and carries at its outer end a nozzle 25 which is located so as to moisten the roller 21 when the atomizer is operated. The bulb of the atomizer is indicated at 26 and is adapted to be compressed by an arm 27 which extends from one edge of the sleeve 14. By means of the spaced disks 22, surplus moisture from the atomizer or from the roller 21 may pass downward and be prevented from being applied to the plain side of the tape, such as would occur if a roller was substituted for the disks 22.

For the purpose of operating the rollers, the shafts of the roller 20 and the disks 22 have secured thereon ratchet wheels 28 which are adapted to be engaged by dogs 29 carried by pinions 30, the latter being loose upon the shafts of the roller 20 and disks 22. Operating in suitable guides 31 depending from the cover plate 11 is a rack bar 32,'the teeth of which engage the pinions 30, so that when the rack bar is moved to the right in Figure l of the drawings, the pinions will be locked to their shafts and the roller 20 and disks 22 will be rotated to feed the tape to the right or into the sleeve 14., A reverse movement of the rack bars will not rotate these shafts as the pinions will revolve freely thereon. The rackbar is moved by means of a bell crank lever 38 which is pivotally mounted upon a bracket 34 extending from the sleeve. 14, one arm of this bracket being connected to the rack bar 32 by means of a link 35. The opposite arm of the rack bar is adjusted as to its length as indicated at 36 and this arm is pivotally connected to astationary lug 37 by a link 38. When the cover plate is pressed downwardly against-the action of the springs 12, the bell crank lever 33 will be rocked upon its pivot and the rack bar moved to the right to rotate the roller 20 and disks 22, the said bar returning to its normal position when the cover plate resumes its normal position,-

without eilecting the operation of the roller 20 and disks 22.

Mounted between the rollers '19 and 21 and carried by the cover plate 11 is a cutter which includes a stationary knife blade 39 and a pivoted knife blade 40, the latter being provided with an extension 41 which is adapted to be engaged by an arm 42 which extends upward from the base 10. lVhen the cover plate is pressed downward, the upper end of the arm 42 will engage the extension 41 of the blade 40 at the proper timeto sever the strip S.

In the operation of the invention, a bundle or other object to be sealed is placed upon the cover plate 11 over the opening 18 and sufiicient pressure is exerted to force the cover plate downward. This downward movement of the plate will feed the strip forward into the sleeve 14 as previously eX plained, the strip at the same time moving downward so as to rest upon a pressure member or bed 43 which will press the strip against the bundle. During the forward movement of the tape, the atomizer will operate to moisten the adhesive and just prior to the limit of movement of the cover plate, the upper end of the arm 42 will engage the extension of the pivoted blade 40 and the latter will be operated to sever the tape. At this point, the rack bar 32 will have moved a sufficient distance to become disengaged from the pinion of the roller 20 so that feeding operation of the tape from the roll 16 will be stopped. The strip which has been out however will continue to move outward'into the sleeve 14 through the continued rotation of the disks 22.

Should the end of'thet-ape fail to tightly adhere to the bundle it may be drawn over a pressure, roller 44 which is located at one end of the pressuremember or bed 43.

The arm 42 is pivotall I mounted upon the base 10 as shown at 45 and its pivotal movement in one direction is limited by an angularly disposed foot 46. A relatively short arm 47 is pivotally secured to the base 10 as shown at 48. A spring 49 is connected to the arm 42 and to the base 10, the purpose being to yieldingly hold the arm 42 against movement in one direction. The arm 42 carries a tooth or lug 50 and when the arm is moved to the position shown by the dotted lines in Figure 3 the arm 47 may be engaged beneath this lug to temporarily hold the arm 42 out of the path of the extension 41' of the knife 40. In this position, the cover plate 11 may be depressed without operating the knife and the strip of tape of any desired length may be withdrawn through the opening 18. p The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.
